Personally, I would drop the docker bit ... running Loki using docker cannot be recommended, as it is not a very persistent solution ... the docker command only really works well for short lived containers.

After all, not even docker-compose can be considered a production ready setup, because it is limited to a single local node, in comparison to the more mature ways (Tanka and Helm).

I guess what could work fine:

• Tanka and Helm as production setups
• docker-compose as a dev setup for quickly trying it out locally
• running the binaries as a last resort if the above won't work

My last company ran all their production containers off of a docker-compose file :)

I get your point, though. I do see value in this in general, if only for documenting how to do it for future contributors or for quickly trying out Loki for evaluation purposes.

We should add a disclaimer to the top of the file to note that we don't recommend using pure Docker or docker-compose in production.

Almost there! Just a few more comments.

I double checked that Docker refers to Docker Compose without the hyphen, this seems to be true.

Thanks!
